Question

5. Is it possible to design a rectangular park of perimeter 80 m and area 400 m²? If so, find
its length and breadth.
​

Answer 1

area=length×breadth

400m²=X×X

400m²=x²

400=x×x

400=20×20

so,length=20

breadth=20

verification:-

perimeter=2(l+b)

80=2(20+20)

80=2(40)

80=80

hence,verified.
